BOOK AND METHOD OF BINDING Filed Jan. 18, 1954 lNV TOR WW. /W M1Patented July 31, 1934 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to an improved book and method of binding thebook. The method is particularly adapted for re-binding books. Thenecessity for economical and satisfactory re-binding is present inpublic libraries and similar institutions. The present method insures astable re-bound book with all the advantages of the binding of a newbook.

This improved method of binding eliminates several objectionablefeatures of the previous rebinding method. In the old method when a bookneeds rebinding the cover is removed, and the book as then formed iscompressed or tapped out to remove the round at the back and the backingjoint. Then the book is sanded or cut at the back which removes thematerial of the pages at the folds which in turn makes the book one ofindividual pages and also removes the stitching. This operation reducesthe back margin. When the book is again sewed the margin is stillfurther reduced. This forms a narrow margin on the inner edge of eachpage which often makes the reading difficult. The original margin of thesewing fold is thus destroyed and a new one established. Newperforations are needed for stitching in the old method and the re-boundbook when opened can not be opened flat for comfortable readingespecially with the narrow margin at the sewing fold.

My invention corrects these faults by providing a re-bound book with theoriginal margin at the sewing fold and in which the originalperforations for stitching are mended.

The invention is also designed to so strengthen the sewing folds of thesections or signatures that the book can be opened flat and freely tothe fold of the section without strain.

The invention also provides a book in which the strain at the sewingfolds is minimized and the pages will not crease or tear down at thesewing fold when constantly turned in use.

The accompanying drawing, as a part of this specification, illustratesthe invention with the parts of a thickness that is necessarilyexaggerated and with spaces between sheets also exaggerated. In thedrawing Figure 1 is an end view of a section consisting of three sheets.Figure 2 is a similar view showing strengthening or bracing strips onthe inner and outer faces of the fold of the section. Figure 3 is aperspective view of a section provided with my improved form ofstrengthening strip. Figure 4 is an end view of the sections assembledand sewed together to form a book. Figure 5 is a perspective view of ashort length of my improved binding strip.

In putting my method into effect the sheets 10 are assembled in theusual way to form a section 11. The sewing fold 12 is provided with astrip 13 on the back of the fold. This strip is pasted on and it isusually a strip of paper gummed on one side. I may also paste a strip ofthe same kind at 14 on the inside of the fold. The sections with theirpasted strips are then assembled as shown in Figure 5 and stitched as at15 to assemble the sections into book form.

The strip 13 of paper or other suitable material is provided with anuneven edge 16. The edge is preferably serrated or scalloped. Thiseliminates a straight edge which straight edge would cause a strain atthe bending edge which eventually creases and breaks or tears the pageunder repeated bending in use. The serrated edge provides a fold or bendthat is not against a sharply defined straight edge and a fuller orrounded bend takes place causing no break or tear in the paper page. I Abook sewn through with my strengthening of the sewing folds of thesections allows the book to open flatly and freely to the fold of thesection without strain and the original margin of the sewing fold ispreserved. The old line of stitching can be used in a re-bound book asthe reenforcing strips mend the original perforation of stitching.

While the method and construction are particularly adapted to re-bindingbooks, it will be evident that they may be employed in the originalbinding if desired.

While I have shown in the drawing strengthening strips on the inner andouter folds of the section, it will be evident that I may use thesestrips on each sheet or fold of a section, distributing them through thesections as the particular circumstances require.

I claim:

1. A book section having a folded strip secured over its folded end,said strip having an edge that is uneven relative to the fold.

2. A book section having a folded strip secured over its folded end,said strip having a serrated edge.

3. A book section having strips with serrated edge pasted over the innerand outer folds of the section. a

4. The method of re-binding books which consists in taking the bookapart in sections, providing the sections with folded strips at thefolds. said strips having serrated edges, then assembling the sectionsand then sewing them together to again form the book.
